Prediction of postnatal circulation in pulmonary atresia/critical stenosis with intact ventricular septum: systematic review and external validation of models

open access: yesUltrasound in Obstetrics &Gynecology, Volume 62, Issue 1, Page 14-22, July 2023., 2023
ABSTRACT Objective A favorable postnatal prognosis in cases of pulmonary atresia/critical stenosis with intact ventricular septum (PA/CS‐IVS) is generally equated with the possibility of achieving biventricular (BV) repair. Identification of fetuses that will have postnatal univentricular (UV) circulation is key for prenatal counseling, optimization of

How to Explain Major Policy Change Towards Sustainability? Bringing Together the Multiple Streams Framework and the Multilevel Perspective on Socio‐Technical Transitions to Explore the German “Energiewende”

open access: yesPolicy Studies Journal, Volume 50, Issue 3, Page 671-699, August 2022., 2022
Most efforts at explaining major policy transformation apply a single lens to study specific cases. Recent contributions have called for a more plural use of theories to facilitate the production of valuable new perspectives and research agendas. The German energy transition is a good example of such a transformative change.

全球变化下九龙江河流-河口系统营养盐循环过程、通量与效应 [PDF]

open access: yes, 2018
河流-河口系统是陆地与海洋物质循环的重要通道。人类活动和气候变化已显著改变营养盐循环并产生一系列生态环境效应(富营养化、有害藻华、缺氧、酸化等)。本文基于现场观测、实验模拟和模型分析结果,总结亚热带中小型河流——九龙江河流-河口系统的营养盐(氮、磷、硅)含量和通量的长期变化及主控因素、水体反硝化作用、梯级电站水库对营养盐的滞留、气候变化(暴雨事件、升温)影响营养盐输送与循环等方面的研究进展,讨论营养盐变化的潜在生态环境效应。与大型河流相比,中小型河流对人类活动与气候变化的干扰更为敏感 ...

Oxygen Vacancy Engineering of Ultrafine ZnAl2O4 Nanoparticles as a Robust Protective Layer for Dendrite‐Free and Long‐Lifespan Aqueous Zn Metal Anodes

open access: yesRare Metals, EarlyView.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

连续降雨作用下褐土坡面侵蚀及其水动力学特征

open access: yesShuitu Baochi Xuebao, 2020
为研究在长时间降雨侵蚀过程中北京褐土坡面侵蚀特征及其水动力学机制,通过室内人工模拟降雨试验,分别在60,90 mm/h雨强下对褐土坡面进行连续10场次降雨试验,探讨了坡面侵蚀过程中的产流产沙特征及其与水动力学参数间的关系。结果表明:(1)在雨强及次降雨量较一致的条件下,随降雨场次增加坡面次降雨产流量变动较小,而次降雨产沙量变化较大,60,90 mm/h雨强下次降雨产沙量的变异系数为23.94%和59.88%,且第10场降雨的产沙量仅为第1场降雨的59.74%和22.28%;(2)连续降雨条件下 ...
